What Is Lactobionic Acid?


Just when you thought you’ve heard them all, a new acid hits the shelves and this one is supposed to help improve winter skin, through its gentle exfoliation.

Lactonionic acid is a high value lactic acid derivative that has potential in skincare as a less irritable AHA (it’s sub-category is a PHA) and while it’s just gaining prominence it’s not exactly new.

In fact this study from ten years ago noted it’s use as a proposed alternative to low‐molecular AHAs in cosmeceuticals.

The same study even suggested that Labtobionic acid it might be more safe and efficacious when compared with Glycolic acid.

What does lactobionic acid do for the skin?

It’s a multitasker.

Lactobionic acid can do it all, it: moisturisers the skin, is an antioxidant and of course exfoliates the skin.

Due to these uses, lactobionic acid, can improve the tone, radiation and elasticity of most skin types.

Is lactobionic acid different to other acids?

It’s primary function of exfoliating the skin is the same as other acids (well apart from hyaluronic acid) so you’re likely to get similar results with using lactobionic acid.

Their main advantage comes from it’s molecule size, as I noted in ‘My guide To Polyhydroxy Acids In Skincare’, the unique properties of PHAs, include it’s larger molecule size and surface level penetration, make them ideal for virtually all skin types but especially if you’ve experienced sensitivity in the past with an AHA- or BHA-based product.
